Illuminance is the total luminous flux incident on a surface per unit area. It is measured in lux (lx).
1 lm/m² = 1 fc·h
1 fc·h = 1 lm/m²
Example:
Convert 15 Lumens per Square Meter to Footcandle Hour:
15 lm/m² = 15 fc·h
| Lumens per Square Meter | Footcandle Hour |
|---|---|
| 0.01 lm/m² | 0.01 fc·h |
| 0.1 lm/m² | 0.1 fc·h |
| 1 lm/m² | 1 fc·h |
| 2 lm/m² | 2 fc·h |
| 3 lm/m² | 3 fc·h |
| 5 lm/m² | 5 fc·h |
| 10 lm/m² | 10 fc·h |
| 20 lm/m² | 20 fc·h |
| 30 lm/m² | 30 fc·h |
| 40 lm/m² | 40 fc·h |
| 50 lm/m² | 50 fc·h |
| 60 lm/m² | 60 fc·h |
| 70 lm/m² | 70 fc·h |
| 80 lm/m² | 80 fc·h |
| 90 lm/m² | 90 fc·h |
| 100 lm/m² | 100 fc·h |
| 250 lm/m² | 250 fc·h |
| 500 lm/m² | 500 fc·h |
| 750 lm/m² | 750 fc·h |
| 1000 lm/m² | 1,000 fc·h |
| 10000 lm/m² | 10,000 fc·h |
| 100000 lm/m² | 100,000 fc·h |
